COLUMN oONsTRUOTION Application filed April 18,

lThis invention relates to a column construction, and refers more particularly to an improvement in decorative or ornamental columns which are especially designed to ena close and conceal the usual structural steel columns.

' Itv has heretofore been the practice in hotel lobbies, banks, theatres or the like to enclose and conceal structural'steel columns with an l Ornamental or decorative column in various ways, such as by applying hollow sectors of marble or stone around the structural column or pouring a cementitious mixture into an ornamental mold or form arranged around the structural column.

In contradistinction to this, the present invention comprehends a fabricated decorative column which includes a framework supported from and braced by the structural column and adapted to VVsupport a cementitious covering with a surface coating applied thereover to give the desired ornamental effeet.

yThe invent-ion further comprehends a yfabricated ornamental or decorative column` construction'which in addition to affording means for producing a wide variety of ornamental elfects, serves to additionally insulate and protect the structural column from fire hazards.

Other objects of the invention reside in the y comparative simplicity of construction of the column, the economy with which it may be produced and lerected and the general eliiciency derived therefrom. Y

VVith'the above` recited and other objects in view, reference ishad to the following description and accompanying drawings, in which there is exhibited one example or embodiment of the invention, vwhile the claims define the yactual scope of the same.

In the drawings- Figure4 1 is a side view of the column, partly broken away and shown in section to disclose the underlying structure. Y

' Figure 2 is a horizontal sectional view on an enlargedl scale, taken approximately on the line indicated at 2-'2 in Figure 1.

Figure 3 is a similar view taken approximately `on theline 3-3 of Figure 1.

1929. serial No. 356,149.

- Figure is a fragmentary enlarged hori zontal sectional view taken approximately on the line indicated at l4 in Figure 1.

Referringto the drawings by characters of reference, A designates a structural steel lH-column which is enclosed in the usual manner by the requisite fireproof covering B.

The ornamental column designated generally by the reference character C, is fabricated from a framework which consists of a pluvrality of vertical elements 5, preferably arfastening elements 9. Under this arrangement, it is obvious that the webs 7 *proj ect radially or outwardly from the rings or bands 8. At the lower end of the column, the framework may be supported in any suitable manner, such as by the angle ring or band 10 to which the lower endsof the uprights are bolted or attached as' lat 11.- The band or ring 10 may in turn be supported by a foot- Y ing composed of vertical angle pieces 12 and a base angle piece 13, as illustrated. In Order to pr-ovidemeans forradially bracing .V

the ornamental column C from the structural column A and to afford means for initially supporting the framework, brace stems 15 are employed, the outer ends16 of which are .thre-icled.v The threaded outer ends 16 are designed to extend through openings in the rings or bands 8 and nuts 17 and 18 clampingly engage the inner and outer peripheries of the rlngs or bands 8. The inner ends of the stems 15 areprovided with horizintally over. If it is desired, the column' shaft mayv be of gradually reducing diameters, and this may be accomplished by employing rings or bands 8 which are gradually reduced in diameter toward the upper end of the shaft, it being understood that the uprights or vertical elements will be bent to conform therewith when bolted to therings or bands 8. The capital of the .column indicated generally bby the reference character D may be Vof any desired construction, the same being illustrated in the present instance as of hollow metal suitably Vsupported and braced from the framework of thek column shaft.

What is claimed is:

l. In a tubular fabricated decorative column adapted to surround and conceal a structural column, a framework including a plurality of vertical annularly arranged elements and a plurality of horizontal vertically spaced bands secured thereto, plastic supporting material carried by the framework, aicementit-ious covering applied to said supporting material and a surface finishing coating applied over said covering.

2. In a tubular fabricated decorative column surrounding and concealing a` struc tural column, a framework including a pluralityof vertical annularly arranged elements and a plurality of vertically `spaced bands secured thereto, brace elements connected with said bands and extending radially inward therefrom, straps embracing the structural column and connected with the inner end of the brace elements, plastic supporting material carried by the frameworl a cementitiouscovering applied to said supporting materialfand a surface finishing coating appliedover said cementitious covering.

3. The combination with a structural-steel column, of a fabricated decorative column surrounding and concealing the first mentioned column, said decorative column including a framework composed of a plurality of vertical annularly arranged T-beams having vthe base flangesdisposed inwardly and the webs projecting radially and a plurality of vertically spaced bands secured to the innerr sides of said base flanges of the T-beams,

" brace rods anchored toV said bancs and eX- tending radially inward therefrom and strap sections embracing the structural column and connected withrthe brace rods.

l. The combination with a structuralY steel column, of a fabricated decorative column surrounding and concealing the first mentioned column, said decorative column including a framework composed of a plurality of vertical annularly arranged T-beams having the base flanges disposed inwardly and the webs projecting radially and a plurality vof vertically spaced bands secured to the inner sides of said base flanges of the T- beams, brace rods anchored to said bands and extending radially inward therefrom, strap sections embracing the structural column and connected with the brace rods, plastic supporting material attached to the webs of the T-beams and bridging the space therebetween, a cementitious covering applied to said supporting material and a surface finishing coating applied over said covering.

5. The combination with a structuralsteel column, of a fabricated decorative column surrounding and concealing the first inentioned column, said decorative column including a framework composed of a plurality of vertical annularly arranged T-beams .having the base flanges disposed inwardly and the webs projecting radially and a plurality of vertically spaced bands secured to the inner sid-es of said base flanges of the T-beams, brace rods anchored to said bands and extending' radially inward therefrom, strap sections embracing` the structural column and connected with the brace rods, plastic supporting materia-l attached to the webs of the T-beams and bridging the space therebetween, a. cementitious covering applied to said supporting material, a surface finishing coating appliedr over said covering and arris strips attached to the webs` of the T-beams and disposed flush with the surface finishing coating.

6. The combination with a structural steel column, of a fabricated decorative column surrounding and concealing the first mentioned column, said decorative column including a framework composed of a plurality of vertically disposed equi-distantly spaced elements surrounding the structural column and a plurality of vertically` spaced bands secured to said vertical elements and means for supporting the framework from and bracing the same by the structural column including brace rods connected with the bandsA and extending radially inward, strap sections encompassing the structuralvcolumn and provided with outturned aperturedears, eyes formed at the inner end of the brace rods disposed between said apertured ears and bolts extending throughvthe apertured ears and the eyes of'saidbrace rods.
